Siheyuan: After Three Years of Signing In, I'm Finally Waiting for You

Yang Weimin walked into the courtyard house and spent three full years before activating the sign-in system. The first sign was a bicycle ticket and canned meat, which he ate while waiting for his grade six fitter grade. There was a lot of chaos in the courtyard, so he closed the door and lived his own life. In this life, he has skills and systems, and it has nothing to do with him whatever the beasts in the courtyard do.
